Direct answer: If your Electrolux dryer runs but does not heat, start with the cycle setting, lint screen, and exhaust airflow. If airflow is poor, the dryer can overheat and trip a safety part. If airflow is good and the drum still stays cold, the usual next suspects are the dryer heating element on electric models or the dryer igniter and related heat-safety parts on gas models.
Most likely: The most common real-world cause is restricted airflow through the lint screen housing or vent, followed by a tripped dryer thermal cutoff or a failed dryer heating element.
First separate no-heat from poor-drying. If the dryer finishes a cycle and the clothes are still cool, treat it as a heat problem. If the clothes get warm but stay damp for a long time, airflow is still the first place to look. Reality check: a dryer can tumble perfectly and still have a dead heat circuit. Common wrong move: replacing the heating element before checking the vent and blowing the new part for the same reason.
Don’t start with: Do not start by ordering a control board or guessing at gas valve parts. On this symptom, airflow and heat-safety parts beat expensive electronics most of the time.
The dryer sounds normal and the timer runs, but there is no warmth inside the drum and clothes come out cold.
Start here: Start with settings, power supply, and airflow. Then move to the heating element on electric models or ignition parts on gas models.
You feel some heat early in the cycle, then the heat fades and dry times get much longer.
Start here: Start with the vent path and lint buildup. That pattern often points to overheating from poor airflow and a heat-safety part opening up.
Clothes eventually dry, but only after multiple cycles, and the cabinet may feel hotter than usual.
Start here: Check outside vent airflow first. A restricted vent is more likely than a failed part when you still have some heat.
You may hear ignition attempts, or see brief heat that does not stay on, while the drum keeps turning.
Start here: After airflow checks, focus on the gas heat side: igniter operation and the dryer thermal cutoff or high-limit safety parts.
This is the most common cause of weak or lost heat. Poor airflow makes the dryer run too hot internally, which can trip safety parts or cycle heat off too early.
Quick check: Run the dryer on a heat cycle with the vent disconnected briefly and safely venting into the room only for a minute or two. If heat or airflow improves sharply, the vent path is the problem.
When a dryer overheats from a blocked vent, one of the heat-safety parts can open and leave you with a dryer that tumbles but will not heat.
Quick check: If airflow was poor before the failure and the dryer now has no heat at all, this moves near the top of the list.
A broken element can leave the dryer running normally with no heat, especially if airflow is decent and the vent is clear.
Quick check: If the dryer is electric, the vent is clear, and you have proper power at the outlet, the heating element becomes a strong suspect.
Gas dryers can tumble with no heat if the igniter does not light the burner or the heat-safety circuit is open.
Quick check: Listen for repeated ignition attempts without steady burner heat after the dryer starts.
A surprising number of no-heat calls come down to air-fluff settings, low-temp options, or an electric dryer running on only part of its power supply.
Next move: If heat returns after correcting the setting or resetting a tripped breaker, run a full load and keep an eye on dry time. You may still have an airflow issue that caused the trouble. If the dryer still tumbles with no real heat, move to airflow checks before assuming a bad part.
What to conclude: You have ruled out the easy false alarms and one of the most common electric-dryer power problems.
Bad airflow is the top cause of long dry times and a major cause of thermal cutoffs opening. It is also the least destructive thing to confirm first.
Next move: If the dryer heats better with the vent disconnected or after clearing a blockage, fix the vent path before replacing any dryer parts. If airflow is strong and the dryer still has no heat, the problem is likely inside the dryer heat circuit.
What to conclude: You have separated a house-side vent problem from a dryer-side heating failure.
Electric and gas dryers lose heat for different reasons. Splitting those paths early keeps you from buying the wrong parts.
Next move: If this clearly points you to the electric or gas heat path, you can inspect and test the right components instead of guessing. If you still cannot tell what path you are on, stop before ordering parts and identify the dryer type from the data label.
Once settings and airflow are ruled out, the next useful move is a visual and continuity check of the heat parts that fail most often on this symptom.
Next move: If you find an open or visibly failed part, replace that confirmed part and correct any airflow problem that likely caused it. If the element, igniter, and heat-safety parts all test good, the diagnosis is no longer a simple common-parts repair.
A dryer that lost heat from overheating will often do it again if the vent restriction is still there. The repair is not finished until the machine heats normally and moves air well.
A good result: If the dryer heats normally and outside airflow is strong, the repair is complete.
If not: If heat is still missing after a confirmed replacement and good airflow, the remaining problem is likely in wiring, power supply, or controls and is worth a pro diagnosis.
What to conclude: You either finished the repair the right way or reached the point where further guessing gets expensive.

Most of the time it is either poor airflow, a tripped dryer thermal cutoff, a failed dryer heating element on an electric model, or a gas ignition problem on a gas model. Start with vent and lint checks before replacing parts.
Yes. A restricted vent can make the dryer overheat and open a safety part, leaving you with a drum that still turns but no heat at all.
On an electric dryer, the heating element becomes a strong suspect when the dryer has proper power, airflow is good, and the element tests open or shows a visible break.
That pattern usually points to airflow trouble first. The dryer overheats, the heat cycles off, and the load never dries normally. Check the vent path before chasing parts.
No. If the thermal cutoff failed because the dryer was overheating, the vent restriction still needs to be fixed. Otherwise the new part can fail again.
Many homeowners can handle lint cleanup, vent checks, and simple part replacement with the dryer unplugged. If you find burnt wiring, repeated breaker trips, or any gas-safety concern, it is time for service.
